Orex Reports 2.7 Metres Grading 840 g/t Silver-Equivalent in a New Target Area on the Coneto Gold-Silver Project in Durango, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 7, 2013) -Orex Minerals Inc. (TSX VENTURE:REX) ("Orex"), is pleased to announce the results of the second batch of holes from the 12,000 metres Phase-II diamond drilling program on the Coneto Gold-Silver Project in Durango, Mexico. A technical committee, with representation of Orex and its project partner Fresnillo PLC (LSE:FRES) ("Fresnillo"), is managing this Phase-II program.

Also in BCO-11 was a La Bufa vein intercept of core length 6.40 metres (true width 5.23 metres) grading gold 2.41 g/t and silver 129 g/t, for a gold-equivalent of 4.87 g/t, or a silver-equivalent of 256 g/t. Within this intercept is core length 2.40 metres (true width 1.96 metres) grading gold 6.08 g/t and silver 187 g/t, for a gold-equivalent of 9.64 g/t, or a silver-equivalent of 506 g/t.

According to Orex's President, Gary Cope, "This is the first reconnaissance drilling in the La Bufa Zone at Coneto. This high grade drill result proves that La Bufa is a promising target area and deserves more detailed drilling."

Holes 7 and 8 were drilled in the Coneto "Central Zone" to target the Sauce vein. Holes 9 to 13 were drilled in the Coneto "La Bufa Zone" to target the La Bufa and the Santo Niño veins.

Silver-equivalent for the purposes of this news release is defined as silver grade plus 52.5 times gold grade. Gold-equivalent is defined as gold grade, plus silver divided by 52.5. The 52.5:1 ratio is based on the spot prices of silver $32/ounce and gold $1680/ounce. Metallurgical recoveries and net smelter returns are assumed to be 100% for the equivalent values. Base metal values are not included in the equivalent values.

Coneto Mining District - Durango, Mexico

The historic Coneto Mining District is situated in the heart of the "Mexican Silver Trend", stretching from Guanajuato in the southeast, through to the states of Zacatecas and Durango. The trend hosts some of the world's largest silver deposits, including Fresnillo, Guanajuato, La Pitarrilla, La Preciosa, Real de Angeles, and Zacatecas mining camps.

Orex and Fresnillo hold extensive contiguous mineral concessions in the Coneto Mining District, which collectively total approx. 17,600 hectares and cover more than 50 known mineralized epithermal quartz veins. The project is located in the Mesa Central, on the eastern flank of the Sierra Madre Occidental Mountains.

Ben Whiting, P.Geo, is a Qualified Person as defined in NI 43-101 and takes responsibility for the technical disclosure contained within this news release.

The drill core sampling has been conducted with a rigorous QA/QC program, incorporating analytical standards and blanks into the sample stream. Analyses were performed in the laboratories of ALS Chemex.

The first six holes of the current drilling program, all in the Loma Verde sector of Coneto, were reported in a news release on November 7th 2012 and are a line of holes drilled beneath the successful Phase-I drilling program (see news releases: July 6th 2010 and August 9th 2010).
